Description
Technical Field
[0001] This application relates to the field of spraying equipment technology, and in particular to a surface hot and cold end spraying device. Background Technology
[0002] Currently, spraying technology is widely used in industrial production, especially in industries such as automotive and aerospace, to improve the corrosion resistance and aesthetics of products. However, traditional spraying equipment often uses spray guns operating at a single temperature, which cannot meet the spraying needs of some special materials or environments. With technological advancements, market demands for spraying equipment are constantly increasing, particularly for equipment capable of operating in different temperature ranges. This requires not only higher precision and stability in spraying equipment but also the ability to reduce costs and improve efficiency while maintaining quality.
[0003] A common problem with existing spraying equipment is that it cannot flexibly adjust the spray temperature, especially when it is necessary to frequently switch between hot and cold spraying modes. In addition, these devices are often bulky, inconvenient to move, and not convenient for on-site operation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a surface hot and cold end spraying device, which overcomes the deficiencies of existing technologies and aims to solve the common problems of existing spraying equipment, such as the inability to flexibly adjust the spraying temperature, especially in situations where frequent changes in hot and cold spraying modes are required; in addition, these devices are often bulky, inconvenient to move, and difficult to operate on-site.
[0005] To achieve the above objectives, this application provides the following technical solution: a surface hot and cold end spraying device, including a support platform, a storage tank above the support platform, a discharge port at the bottom of one side of the storage tank, a conveying pump installed at the other end of the discharge port, a temperature control unit installed at the output end of the conveying pump, and pipe connections between the temperature control unit, the conveying pump, and the storage tank. The temperature control unit includes an installation box, a cold pipe, and a hot pipe. The cold pipe and the hot pipe are installed inside the installation box, and both the cold pipe and the hot pipe are connected to external pipes. Multiple sets of cooling fins are installed outside the cold pipe, and multiple sets of heating pipes are installed outside the hot pipe. A compressor is installed on one side of the temperature control unit. A three-way temperature control valve is installed at one end of each of the cold pipe and the hot pipe, penetrating one side of the temperature control unit. A spray pipe is installed at the other end of the three-way temperature control valve.
[0006] By adopting the above technical solution and setting up a temperature control unit, the delivery pump can draw paint from the storage tank during use.

Finally, it passes through a three-way temperature control valve and is delivered into the spray pipe, allowing workers to directly perform spraying operations. This setup allows workers to directly adjust the three-way temperature control valve to regulate the spray temperature. In work environments requiring frequent temperature changes, dynamic temperature adjustment is easily achieved, ensuring the spray temperature remains stable over a wide temperature range.

[0017] As a preferred technical solution of this application, four sets of barrier bars are provided above the support platform, and a support plate is installed at the bottom of the storage tank.
[0018] By adopting the above technical solution and setting up barrier bars, the various components above the support platform can be protected to a certain extent during use, thus improving the practicality of the device.
[0019] As a preferred technical solution of this application, multiple sets of reinforcing rods are installed between the two sets of movable handles, and anti-slip sleeves are installed at the other end of both sets of movable handles.
[0020] By adopting the above technical solution and setting up a reinforcing rod, the stability of the connection between the two sets of moving handles can be improved, and the anti-slip sleeve can play an anti-slip role.
[0021] The beneficial effects of this application are:
[0022] 1. By setting up a temperature control unit, the delivery pump draws paint from the storage tank during use. The paint then passes through the temperature control unit, undergoing heating and cooling via cold and hot pipes respectively.

The cold pipe 402 and the hot pipe 403 are both connected to external pipes. Multiple sets of cooling chips 405 are installed outside the cold pipe 402, and multiple sets of heating pipes 404 are installed outside the hot pipe 403. A compressor 406 is arranged on one side of the temperature control unit 4.

The control panel 8 is electrically connected to the three-way temperature control valve 5, the small controller 601 and the delivery pump 3.
[0031] By incorporating a temperature control unit 4, the delivery pump 3 draws paint from the storage tank 2 during operation. The paint then passes through the temperature control unit 4, undergoing heating and cooling via the cold pipe 402 and hot pipe 403 respectively. Finally, it passes through a three-way temperature control valve 5 and is delivered into the spray pipe 6, allowing workers to directly perform spraying operations. This design allows workers to directly adjust the temperature of the sprayed material by adjusting the three-way temperature control valve 5. In work environments requiring frequent temperature changes, dynamic temperature adjustment is easily achieved, ensuring the sprayed material remains stable over a wide temperature range to meet the needs of different workpiece types. It supports seamless switching between hot and cold spraying modes, significantly improving the equipment's flexibility and adaptability, expanding its application areas, and enhancing its practicality. Furthermore, the inclusion of a small controller 601 facilitates rapid temperature control during spraying, further enhancing the device's usability.
[0032] Reference Figure 1A filter mechanism 7 is installed between the conveying pump 3 and the discharge port 202. The filter mechanism 7 includes a mounting plate 701 and a filter box 702. The mounting plate 701 is located on one side of the filter box 702, and multiple sets of filter screens 703 are installed on one side of the mounting plate 701.

Four sets of mounting slots 101 are opened at the bottom of the support platform 1, and each of the four sets of mounting slots 101 is rotatably connected to a moving wheel 102. Two sets of moving handles 9 are provided on one side of the support platform 1, and the bottom of each set of moving handles 9 is fixedly connected to one side of the support platform 1. By setting up the filter mechanism 7, the feed material can be filtered when the delivery pump 3 is working. Furthermore, the separation between the mounting plate 701 and the filter box 702 allows for the replacement and maintenance of the filter screen 703, improving the filtration efficiency of the device and minimizing subsequent clogging of the spray pipe 6. By setting up the mounting groove 101, the device can be moved more easily during use using four sets of casters 102, making it easier to move the device. By setting up the moving handle 9, it is easier and less strenuous for operators to move the device.
[0033] Reference Figure 1 The temperature control unit 4 has multiple temperature controllers installed inside, all of which are electrically connected to the control panel 8. By setting temperature controllers, accurate detection of the internal temperature of the temperature control unit 4 can be achieved more conveniently, improving the practicality of the device. Four sets of baffles 103 are installed above the support platform 1, and a support plate 201 is installed at the bottom of the storage tank 2. The baffles 103 provide a certain degree of protection for the components above the support platform 1 during use, improving the practicality of the device. Multiple reinforcing rods 901 are installed between the two sets of moving handles 9, and anti-slip sleeves 902 are installed at the other end of each set of moving handles 9. The reinforcing rods 901 improve the stability of the connection between the two sets of moving handles 9, and the anti-slip sleeves 902 provide an anti-slip effect.
[0034] Working Principle: By incorporating a temperature control unit 4, the delivery pump 3 draws paint from the storage tank 2, which then passes through the temperature control unit 4. The paint is heated and cooled by the cold pipe 402 and hot pipe 403 respectively, and then simultaneously flows through the three-way temperature control valve 5 before being delivered into the spray pipe 6. This allows workers to directly perform spraying operations. During operation, workers can directly adjust the three-way temperature control valve 5 to regulate the temperature of the sprayed paint. This is particularly useful in work environments requiring frequent temperature adjustments. The dynamic adjustment of the spraying temperature allows the spray material to remain stable over a wide temperature range, thus meeting the needs of different types of workpieces. It supports seamless switching between hot and cold spraying modes, significantly improving the flexibility and adaptability of the equipment, expanding the application field, and enhancing the practicality of the device. By setting up the filter mechanism 7, the feed material can be filtered when the delivery pump 3 is working. Furthermore, the separation between the mounting plate 701 and the filter box 702 enables the replacement and maintenance of the filter screen 703, improving the filtration efficiency of the device and minimizing subsequent clogging of the spray pipe 6.
[0035] Among them, by setting up a small controller 601, it is more convenient for workers to quickly control the spraying temperature during the spraying process, which improves the practicality of the device. By setting up the mounting slot 101, the device can be moved more easily by four sets of moving wheels 102, which saves more effort when moving the device.
[0036] Meanwhile, by setting a temperature controller, it is more convenient to accurately monitor the internal temperature of the temperature control unit 4, thereby improving the practicality of the device;
[0037] In addition, by setting the movable handle 9, it is more convenient and less strenuous for the staff to move the device during use; by setting the barrier bar 103, it can provide a certain degree of protection for the various components above the support platform 1 during use, thus improving the practicality of the device; by setting the reinforcing bar 901, the stability of the connection between the two sets of movable handles 9 can be improved, and the anti-slip sleeve 902 can play an anti-slip role.
